Specification of Letters Patent. Application filed April 17, 1908. Serial No. 427,753.

Patented July 5, 1910.

To all whom 'it may concern:

Be it known thatI, Orro BRticKn, a citizen of the German Empire, residing at F rankfort-on-the-Main, Germany, have invented new and useful Improvements in Apparatus for the Purification of Oils and Similar Bodies, of which the following is a specification. I

My invention relates to an apparatus for the purification of oils, fats, and particularly fatty acids, but which may be used for a number of purposes-in the chemical or physical treatment of various liquids.

In describing my invention I will refer to the accom anying drawings in which-- Figure 1 ifiustrates a central longitudinal section of an apparatus embodying my invention, and Fi s. 2 and 3 are similar .views illustrating mo ified constructions.

Referring to Fig. 1, 1). represents a hollow body or cylinder which is t'elescoped in theend of a arger hollow body on cylinder e, the smaller cylinder extending for-a greater portion'of its length within the larger cylinder, but leaving a space at the bottom of the larger cylinder, as clearl shown. While the two hollow bodies I) and e are shown as cylinders, it is to.be understoodthat they may be rectangular in cross section, or of any other desired shape. The cylinder e, is made suificiently large to afford a space m between the wall of the twocylinders for the passage of the waste gases and the liquid being treated, as will described. Connected with the bottom of the smaller cylinder 6, is a pipe a, which passes downwardly through the bottom of the larger cyl'nd'er e, a suitable packing being provided bet een said pipe and the bottom of the cylinder 6, said pipe constituting the inlet pipe for the liquld to be treated. A horizontal row of holes (1, is provided through the wall of the inner cylinder at a point at some distance above the bottom thereof to afford passages through which the liquid may pass from the smaller cylinder to the space at between the two cylinders, and above said row ofholes there is another series of holes is for the passage of waste gases and vapors from the outer to the inner cylinder, the said gases or va orspassing from the inner, ylinder throug a pipe 2' at the upper end thereof. The steam, air, or other agent which is to be employed to act on the liquid to be treated, passes into the smaller cylinder through a be hereinafter with the treate pipe which enters the cylinder near'the top thereof and extends downwardly to a'point near the bottom of the cylinder where it terminates in arose 9 through which the treating agent issues in a series of fine streams. The treating agent is also supplied to the outer or larger cylinder through an inlet pipe 72. which is located above the outlet f through which the treated liquid is discharged from the apparatus.

As hereinbefore indicated, the apparatus described may be used for a number of purposes in the'chemical or physical treatment of various liquids. Forinstance, by passing heated oil or aqueous solutions, such asbrine, in a continuous current through the pipe a, and inti'oducin steam or other heating vapor through t e pipes g and h, an evaporation or purification may be effected. For instance, oilsmay be freed of volatile constituents, or brine and other solutions may be evaporated. The apparatus may also be usefully employed for the chemical treatment of various materials with air and other ases as for instance in blowin linseed oil,

and other fat oils. For this purpose a current of linseed or duced ina continuous current through the pipe (1: while air is blown through the pipes g and h. lhe liquid to be treated passes through the ipe a into the smaller. cylinder 6, which it lls up to the row or series of openings or holes 03, the liquid at this point passing through said openings and flowing in a thin film or stream down the outer side of the wall of the inner cylinder to the bottom of the larger cylinder 6, and then out of the apparatus through the outlet pipe 7. The steam, air, or other treating agent is supplied to the innercylinder through the rose 9 which is submerged in the liquid being treated, the treating agent passing up through the liquid to cause a thorough contact or intermin ling of the treating agent liquid, so that the latter may be heated, evaporated or aerated as the case may be. The treated liquid passes from the inner or smaller cylinder 6 through the holes (Z, and as it passes down the outside of said cylinder in a thin film or sheet, it is further subjected to the treating agent which passes into the outer cylinder through the pipe [2. and ascends into the space m between the two cylinders. The waste gases and vapors in the smaller cylinder escape through the outlet 2', while the gases and vapors in other oil maybe introder 1) is made somewhat longer than the outer cylinder 6, and extends both above and below the same. In this instance the liquid to be treated is admitted to the outer cylinder 6 through a pipe a, and ascends in said cylinder to the openings at through the wall of the inner cylinder, the liquid then described.

scending along the inner surface of said cylinder in a thin film to and through the outlet f. The treating agent is supplied through a spraying rose 1 in the outer cylinder, and through a spraying nozzle 9 in the inner cylinder, the operation being the same as that described in connection with Fig. 1, except that the liquid to be treated passes through the apparatus in a reverse direction.

. The construction illustrated in Fig. 3 corresponds substantially with that illustrated in Fig. 1, except that in the structure of Fig. 3, a jacket 0 is provided around the inner cylinder 1), this'structure being more especially intended where the apparatus is to be used simply for heating or for cooling puroses. The heating or cooling agent is ad mitted to. the jacket through a pipe 0' and passes out through a pipe 0 to the circulating'or outlet pipe 0 The cooling or heating agent is also supplied to the inner cylinder (1 through the spraying rose 9, as before defluid to be heated or cooled, may be either The direction of circulation of the the same as that described in connection with Fig. 1, or in a reverse direction as re- Q ferred to with reference to Fig. 2. In either case, the liquid being treated comes in actual contactv with the heating or cooling agent only as it passes throu h the inner cylinder b.

Various other mo iifications might be made in the apparatus without departing from the main feature of 'my inventlon but those illustrated are deemed sufficient for the purposes of thiss ecification.

- Having thus descri ed my invention, what I claim as new and desireto secure by Letters Patent is:

' In an apparatus for the treatment of fluid substances, the combination of a pair of hollow bodies one being inserted within the other, pipes communicating with the inner and outer bodiesrespectively for the passage through the apparatus of the liquid to be treated, one of said pipes forming the inlet and the other the outlet for the liquid, openings in the wall of the inner body above the inletpipe forming communicating passages between the inner and outer bod1es, and pipes communicating withthe inner and outer bodies for supplying the treating agent.

In testimony whereof I have signed my name to this'specification in the presence of two subscribing witnesses.
